Embodiments of the invention are generally directed to a system for cataloging images based on a gridded color histogram analysis. The system for cataloging images based on a gridded color histogram analysis can be a standalone application for searching an image gallery stored on a user computing device and/or it can be a separate application that a user can assess an image gallery stored on a user account at a third party image storage, or an image gallery searched on the web. The user creates a profile where personal characteristics are uploaded and previous searches are saved. The user is able to establish sampling rules or is able to choose from predetermined sampling rules. The user can customize the frame size for the cataloging image selection. The user can perform a search of an image gallery by either of the following methods. The user can select a region on a gridded template and then select a color combination from a color selection panel which is to be searched in the selected region for all of the images in the gallery. The user to select certain colors that appear only in a designated portion or the region (e.g. selected frame) of an image to search images and sorting images accordingly. The user can also select a specific color from a sample image and the image gallery can be searched for all images that contain that specific color in the same region as the sample image. A color based histogram algorithm is performed on the image gallery based on the method of the search. Gridded color histogram information is extracted from each of the images in the gallery. The pixels in the selected region with the specific color are averaged. The images in the gallery or on the cloud are analyzed for a similarity of color in the specified region. A color histogram catalog sorted by similarity is created as a result of the algorithm. The catalog is transmitted to the user.

FIG. 1 is a functional block diagram illustrating a system for cataloging images based on a gridded color histogram analysis 100, in accordance with an embodiment of the present invention.

The system for cataloging images based on a gridded color histogram analysis 100 includes a user computing device 120 and a server 130. The user computing device 120 and the server 130 are able to communicate with each other, via a network 110.

The network 110 can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and can include wired, wireless, or fiber optic connections. In general, the network 110 can be any combination of connections and protocols that will support communications between the user computing device 120 and the server 130, in accordance with one or more embodiments of the invention.

The user computing device 120 may be any type of computing device that is capable of connecting to the network 110, for example, a laptop computer, tablet computer, netbook computer, personal computer (PC), a desktop computer, a smart phone, or any programmable electronic device supporting the functionality required by one or more embodiments of the invention. The user computing device 120 may include internal and external hardware components, as described in further detail below with respect to FIGS. 7 or 8. In other embodiments, the user computing device 120 may operate in a cloud computing environment, as described in further detail below with respect to FIGS. 9 and 10.

The user computing device 120 represents a computing device that includes a user interface, for example, a graphical user interface 122. The graphical user interface 122 can be any type of application that contains an interface to perform a gridded color histogram image search via a color histogram image module 160 and receive and display the cataloged results from a color histogram based image catalog manager module 140.

The user computing device 120 includes an image gallery 124 that could be the user's personal image gallery. For simplicity, the image gallery 124 is shown as a part of the user computing device 120. However, it can be a separate application hosted on the server 130 that the user can access to search online galleries, or search images on the cloud or the internet.

The server 130 includes a communication module 132, the color histogram based image catalog manager module 140, and the color histogram image module 160. For simplicity, the color histogram image module 160 and the color histogram based image catalog manager module 140 are shown as a part of the server 130. However, the color histogram image module 160 and/or the color histogram based image catalog manager module 140 can be a standalone application on the user computing device 120. The server 130 is able to communicate with the user computing device 120, via the network 110. The server 130 may include internal and external hardware components, as depicted and described in further detail below with reference to FIG. 8. In other embodiments, the server 130 may include internal and external hardware components, as depicted and described in further detail below with respect to FIG. 9, and operate in a cloud computing environment, as depicted in FIG. 10.

The communication module 132 is capable of receiving a gridded color histogram image search from the color histogram image module 160 and transmitting the cataloged results from a color histogram based image catalog manager module 140 to the user computing device 120, via the network 110.

The color histogram based image catalog manager module 140 incudes a user profile database 142, a service profile database 144, a sampling rule collector module 146, a user categorizer module 148, a color histogram algorithm module 150, a color histogram catalog module 152, and a color histogram catalog service daemon 154.

The user profile database 142 and the service profile database 144 are data stores that store previously obtained data. The user profile database 142 stores color histogram sampling rules chosen or created by the user from the sampling rule collector module 146. The user profile database 142 also stores cataloged image galleries from the color histogram catalog module 152. The user specific data stored in the user profile database 142 provides for transparent searches that are geared toward the specific user. The user profile database 142 transmits the user's profile to the user categorizer module 148. The service profile database 144 stores color histogram sampling rules that are predefined by the service provider from the sampling rule collector module 146.

The sampling rule collector module 146 collects all of the sampling rules from the user's and the service providers for customization and optimization of the searches. For example, a sampling rule could be to focus on certain objects, ignore certain objects, filter out a certain color, assign a different weight to certain red, green, or blue color, and/or any customized rule. The sampling rule collector module 146 retrieves sampling rules made by the user from the color histogram catalog service daemon 154 and then transmits them to the user profile database 142 to be stored. The sampling rule collector module 146 obtains the predetermined sampling rules from the service providers and then transmits them to the service profile database 144.

The user categorizer module 148 categorizes user groups according to their user personal characteristics stored in the user profile database 142. The user categorizer module 148 categorizes users into user groups based on similar sampling rules and similar searches of the image gallery 124. This allows for optimization of searches for returning users. The user categorizer module 148 retrieves user information from the user profile database 142 to perform more personal searches, which remember the user's past search inputs and sampling rules. The user categorizer module 148 transmits the user's profile to a catalog control panel 162 so it remembers the user's information.

The color histogram algorithm module 150 provides operations to digitize the distribution of colors pixels in images based on the given sampling rules and frame selector. The color histogram algorithm module 150 retrieves the user chosen sampling rules from the sampling rule collector module 146 and retrieves the frame selection from the color histogram catalog service daemon 154. The color histogram algorithm module 150 is granted access to the image gallery 124. The color histogram algorithm module 150 calculates and extracts gridded color histogram information from the image of the image gallery 124. The color histogram algorithm module 150 performs its calculations based on which method the user chooses to search the image gallery 124. The user can select a region on a gridded template and then select a color combination from a color selection panel which is to be searched in the selected region for all of the images in the image gallery 124. The user to select certain colors that appear only in a designated portion or a region (e.g. selected frame) of an image to search images and sorting images accordingly. The user can also select a specific color from a sample image and the image gallery 124 can be searched for all images that contain that specific color in the same region as the sample image. The color histogram algorithm module 150 retrieves the method that the user took for the search from the color histogram catalog service daemon 154. The color histogram algorithm module 150 averages the pixels in the specified region with the specified color based on the user's search. The color histogram algorithm module 150 then analyzes the images in the image gallery 124 being searched for similarities in color in the specified region. The color histogram algorithm module 150 sorts the images based on those with the most similarities. The color histogram algorithm module 150 transmits the sorted similar images to the color histogram catalog module 152 to be cataloged.

The color histogram catalog module 152 retrieves the similar images from the color histogram algorithm module 150 to catalog them based on their similarities. The color histogram catalog module 152 transmits the catalog to an image gallery layout module 168 to be displayed on the user computing device 120, via the graphical user interface 122. The color histogram catalog module 152 also transmits the cataloged image gallery to the user profile database 142 to be stored for future searches.

The color histogram catalog service daemon 154 receives the user search from an image selector module 166. The color histogram catalog service daemon 154 is granted access to the image gallery 124 being searched. The color histogram catalog service daemon 154 receives the sampling rules from the catalog control panel 162. The color histogram catalog service daemon 154 receives the user's frame selection from a frame selector module 164. The color histogram catalog service daemon 154 transmits the sample rules from the catalog control panel 162 to the sampling rule collector module 146. The color histogram catalog service daemon 154 transmits the frame selection from the frame selector module 164 and the user search and the image gallery 124 from the image selector module 166 to the color histogram algorithm module 150.

The color histogram image module 160 includes the catalog control panel 162, the frame selector module 164, the image selector module 166, and the image gallery layout module 168.

The catalog control panel 162 is where the user can select predetermined sampling rules from the service providers or can write their own sampling rules. The catalog control panel 162 transmits the user's sampling rules and the user's profile to the color histogram catalog service daemon 154. The catalog control panel 162 receives the user's personal characteristics and profile from the user categorizer module 148 so it remembers the user's information.

The frame selector module 164 allows the user to select the frame size to search within the image gallery 124. The frame selector module 164 allows the user to select the grid size, for example 4×4, 8×8, or uneven frames. This allows for easy region selection in the image selector module 166. The frame selector module 164 transmits the user's frame selection to the color histogram catalog service daemon 154 and the image selector module 166.

The image selector module 166 allows the user to search the image gallery 124 based on two different methods. The user can select a region on a gridded template and then select a color combination from a color selection panel which is to be searched in the selected region for all of the images in the image gallery 124. The user can also select a specific color from a sample image and the image gallery 124 can be searched for all images that contain that specific color in the same region as the sample image. The sample image is from the image gallery 124, for example the sample image can be from the user's personal image gallery, from a search on the World Wide Web, or an image gallery stored on a user account at a third-party image storage. The image selector module 166 retrieves the user's frame selection form the frame selector module 164 for accessibility when selecting the specific region on the template or sample image. The image selector module 166 transmits the user's search to the color histogram catalog service daemon 154.

The image gallery layout module 168 receives the cataloged image gallery based on the similarities to the user's search from the color histogram catalog module 152. The most similar images are presented first in the cataloged image gallery. The graphical user interface 122 displays the cataloged images from the image gallery layout module 168 for the user.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.

Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.

Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring now to FIG. 9, illustrative cloud computing environment 50 is depicted. As shown, cloud computing environment 50 includes one or more cloud computing nodes 10 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 54A, desktop computer 54B, laptop computer 54C, and/or automobile computer system 54N may communicate. Nodes 10 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 50 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 54A-N shown in FIG. 9 are intended to be illustrative only and that computing nodes 10 and cloud computing environment 50 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).

Referring now to FIG. 10, a set of functional abstraction layers provided by cloud computing environment 50 (FIG. 9) is shown.
